"Dexter:" Season 5 preview, sort of...

What happens at Comic-Con doesn't stay at Comic-Con, as evidenced by this rather bizarre sneak peek at "Dexter Season 5," to begin Sept. 26.  

  Through the fog and distance, hardcore fans should be able to channel some interesting vibes, but I'm somewhat at a loss.

  I expect the full trailer to be made available by Showtime a little later today. In the meantime, enjoy . . . Sort of.
